LYDY加药装置中加药泵电机发热卡死转不动的原因
LYDY加药装置在使用中，经常发现加药泵电机发热不工作。电机故障的主要原因如下：
1、马达转向不正确，导致泵内部零件卡住
2、泵的内部驱动部件卡住，导致电机过载
3、泵液压端内部压力过大，导致电机过载
4、环境温度过低，加药装置的加药泵内润滑油粘度过高，导致电机过载
相应的解决方案如下：
1、更换马达接线并调整马达转向
2、检查泵驱动箱的内部并更换有故障的零件
3、断开LYDY加药装置加药泵进出口管，释放计量泵内部压力
4、更换润滑油牌号。
成套加药装置加药泵使用时电机发热原因分析
1、润滑油油位过低，导致运动部件润滑不足，部件过热
2、润滑油牌号不对
3、联轴器和电机适配器之间的摩擦
4、加药装置加药泵的电机转子和定子之间出现间隙
相应的解决方案如下：
1、加润滑油至规定油位，以保证润滑效果
2、更换正确牌号的润滑油
3、调整碱液加药泵联轴器安装位置，避免摩擦
4、修理马达。
The cause of heating and sticking of the dosing pump motor in lydy dosing device
Lydy dosing device in use, often found that the dosing pump motor heating does not work. The main causes of motor failure are as follows:
1. The incorrect steering of the motor causes the internal parts of the pump to get stuck
2. The internal drive part of the pump is stuck, causing the motor to overload
3. The internal pressure of the hydraulic end of the pump is too high, resulting in the overload of the motor
4. When the ambient temperature is too low, the viscosity of the lubricating oil in the dosing pump of the dosing device is too high, resulting in the overload of the motor
The corresponding solutions are as follows:
1. Replace the motor wiring and adjust the motor steering
2. Check the inside of the pump drive box and replace the faulty parts
3. Disconnect the inlet and outlet pipes of lydy dosing device dosing pump to release the internal pressure of metering pump
4. Change the brand of lubricating oil.
Cause analysis of motor heating of dosing pump in complete dosing device
1. The lubricating oil level is too low, resulting in insufficient lubrication of moving parts and overheating of parts
2. Wrong brand of lubricating oil
3. Friction between coupling and motor adapter
4. There is a gap between the motor rotor and stator of the dosing pump of the dosing device
The corresponding solutions are as follows:
1. Add lubricating oil to the specified oil level to ensure the lubricating effect
2. Replace the correct brand of lubricating oil
3. Adjust the installation position of alkali dosing pump coupling to avoid friction
4. Repair the motor.
